Common Applications

5.1DVD Authoring

Dolby products are often used in the process of authoring DVD discs. The process requires a DP569 and DP562. A DP572 is also required if the audio is supplied in Dolby E. Using the DolbyRemote software and Dolby Digital recorder package increases ease of use. The Dolby Digital Recorder software utility runs on a Windows 95/98/NT computer with a digital I/O soundcard. It is used to produce .ac3 format files. Figure 5-1 shows the audio equipment in a typical DVD encoding system.

Dolby Laboratories can also supply an interface kit to aid the installation of this system into studios that use either all balanced or unbalanced digital audio connections. This kit is called the DVD-Audio cable kit (Cat. No. 541) and contains four BNC cables along with four impedance transformers. Three of the transformers are female XLR-to- BNC connections, and the other has male XLR-to-BNC connections.

5.2Monitoring Dolby E/Dolby Digital and Dolby Surround Production

When a 5.1 mix is being created, and a Dolby Surround encoded mix will also be created, the effects of both processes should be monitored.
